JOSEPH B. SCHAEFFER, OF PINE FORGE, PENNSYLVANIA.

Patented Mar. 6, 1917.

"Application'led August 13g/1915." Serial No. 46,117.

To all whom z't may concern.'

Be it known that I, Josnrrr B. SCHAEFFER, a citizen of the United States, residing at Pine Forge, in the county of Berks, State of Pennsylvania, have invented certain new and useful Improvements in Egg-Testers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in eggtesters.

An object of-the invention resides in the provision of a device by means of which the fertility of an egg may be ascertained.

A further object of the invention resides in the provision of a device which will be inexpensive to manufacture and simple to operate..

lith these and other objects in view, such as will appear as my description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claim.

In the drawing:

Figure l is a longitudinal sectional view of my device;

Fig. 2 is a bottom plan View;

Fig. 3 is a view looking in the large end of the device; and

Fig. l is a similar view looking at the opposite end.

Referring to the drawing by reference characters wherein like parts are indicated by like characters throughout the several views:

In the embodiment of the invention shown in the drawing, I have illustrated a casing l which is made of any suitable light and flexible material. This casing is tapered from one end to the other and is open at both ends, the contour of the Y,end 2 being such that thedevice may be readily fitis provided with an opening 3 at the bot-# ted to the face of the user. The casing la Itom thereof.- Locatedv in the small end of the casing lis a wall @which is provided with an opening 5- adjacent the opening 3 in the casing l. Extending upwardly from this wall 4 is a /defl'ector plate 6 which is arcuate in cross section and which is so arranged that the rays of lightV will be reiiected through the opening 5.

In using the device the small end is placed near a light and the largev end of the casing is placed to the face of the user. The light will be visible through the opening 5 in the wall a. The egg is inserted into the casing through the opening 3 therein.

The presence ofthe light behind the egg' will render the egg translucent so that the user may see through the same to determine whether or not it is fertile.

It will thus be seen that I have provided very simple device for testing the fertility v of eggs.

While I have illustrated and described a i particular embodiment of my invention, it has merely been for the sake of convenience and I do not wish to be limited to that particular embodimentv as it is obvious that numerous changes may be made in the details of construction without departing from the spirit of the invention or exceeding the scope of the appended claim.

Vhat I claim is v An 4eggtester comprising a substantially frusto-conical casing having A its ends o-pen and an opening in the bottom adjacent the smaller end thereof, a transverse wall in the small end of the casing having an opening at the bottom thereof, and a deflector plate extending in an inclined direction from said wall and the edge of the opening therein to the adjacent end of said casing.

In testimony` whereof, I affix my signature, in the presence of two W'neSSS.

JOSEPH B. SCHAE-FFER.
